South Australia. 5000 Complete Specification for the invention entitled: "PEST COLLECTION DISPOSAL DEVICE" The following statement Is a full description of this Invention, Including the best method of performing it known to me us: PEST COLLECTION AND DISPOSAL DEVICE FIELD OF INVENTION This invention relates to pest collection and disposal devices which provide foz the collection of pests such as flies and other household insects from accessible and from relatively inaccessible locations and for the disposal of pests thus collected. More particularly this invention relates to a pest collecticin and disposal device having a disposable-replaceable cartridge positioned in a duct of the device and through which flows an air stream having pests entrained in the air stream.

BACKGROUND ART Pest collecting devices are well known in the art. These include gum sticker strips as well as the portable, electric gun devices of U.S. Patents 4,488,331; 4,674,458 or 4,607,457. Although these Sdevices utilize a vacuum or suction accompanying an air stream generated by an electric fan, they do not provide for a disposable cartridge which has a builtin, insect retaining means and which closes automatically to entrap an insect. Other known insect trapping devices currently available and which have been available for a number of years are fly swatters, poison sprays and fly papers. However these tech- T niques for capturing' insects are generally disagreeable and unsightly.

DETAILED DESCRIPTION Referring now to the drawings wherein like numerals designate like elements, the device of the 7 ia invention, indicated generally by reference numeral d 5, comprises a housing having air flow passages exif tending therethrough and which includes an integral elongated tubular air duct segment 6. A rotating fan 7 causes an air stream to flow in the air passages.

Air enters an inlet to the duct 6, flows through the device in the direction as indicated by the arrows and is then exhausted from the housing.

The housing includes an integrally formred motor compartment 8 to receive and house an electric motor Ba, and, an integrally formed fan compartment9 for receivingc the fan 7 which is coupled *to a drive shaft 10 of che motor. The fan compartment 9 forms part of the air flow passage. The motor 8a may be driven by an AC current supply but preferably is driven from a DC power source comprising batteries 11 which are shown positioned in an integral handle segmlent 12 of the housing. A trigger switch 13 is provided to control the application of electrical. power from thle batteries to the motor and to thereby Initiate and terminate rotation of the fan 7. Switch 13 is electrically coupled to the batteries 11 and to the 4 motor Ba for energization of the motor upon actuation of the switch. The D.C. batteries may be coupled to an AC power source through a well known battery charging means for maintaining the batteries in a Vcharged state. A battery charger such as charger 47 of, Figure 9 may be associated with a storage rack 52 of Figure 9, In which thle device 5 is positioned and is stored while charging batteries and until ready to 1e used. Preferably the storage rack 52 is attached to a surface such as a wall by conventional means such as screws.

-0- IIt is preferable that one or more elongated, hollow air duct members, shown to be tubes 14, are provided to form an extendable and retractable array which extends the length of duct and the air flow passage. These members are positioned in the air duct segment 6 for telescopic adjustment. Air flowing to the duct segment 6 enters an air inlet opening 21 of I the tube 14 and flows through a constricting noizle This arrangement permits the air nozzle 15 to be spaced apart both from the noise of the motor and from the operator. It also facilitates placement of the nozzle at relatively remote and difficult to Ireach locations such as areas behind furniture or inside cabinets and to reach insects near ceilings. A 153. lamp 16 is provided to illuminate areas and to aid in locating insects where lighting is dim.

A disposable, elongated tubular shaped insect j collecting cartridge 17 is provided as illustrated in the embodiment of Fig. 1i. Cartridge 17, which is adapted to enable air flow therethrough in the direction of its elongated longitudinal axis, is fitted into an integrally-formed cartridge holder cavity segment 18 of the housing. Upon. actuation of the fan 7, an air stream is established and air is drawn into the inlet 21, flows through the constriction through'the tubular passage 19-of tubular duct member 14 which is positioned in duct member 6, through the cartridge 17, and through an air channel 20 of the fan compartment 9 from which it is exhausted through a housing air outlet 22.

9p~ ~In~ the embodiment shown in Fig. 1, there is postioedin the cartridge holder cavity segment 18 Ia pair of annular, elastomeric gaskets 41. One such gasket is shown enlarged in, Figure 5. A first of these gasket is located adjacent an inlet end 42 of the cavity and a second gasket is located adjacent an I outlet end 43 to form an air, tight seal between the cartridge 17 and the air duct 6. A spring 48 posi- I tioned adjacent gasket 41 at the outlet end 43 establishes an axial force sufficient to achieve flexible yet air tight contact with the cartridge in the a,.r duct.

Upon rotation of, the fan 7, an air stream 4flows which reduces the :pressure and creates a suction in the air channel ;20 and in the cartridge 17.

This suction causes a closure member comprising a cartridge flap 26, described below, to flex inwardly I from *an initial closed 'position and to provide an entrance to the cartridge 17.: An insect entrained in the air stream 'will be carried into the cartridge 17 1by the surge of air of the stream. This surge of air helps capture the pest' before escape flight can occur. An insect or pest becomes entrained in the air stream by positioning the inlet-, nozzle near the in- 4 25. sect.

The cartridge 17 comprises an elongated hollow 4body 23 shown to be tubular shaped. It is preferably formed of a stiff plastic such as a polyethylene -4'which is sized to fit into the cartridge holder cayity segment 18 oE the housing,. In an alternative embodiment the cartridge 17 is positioned in a duct member such as the telescoping duct member 32 as illustrated in Figure 3 which includes an insect catching deflector 33 near an iinlet. An air pervious filter means comprising a screen or porous fiber packing 25 is also provided for the cartridge. This filter means intercepts and': filters from the air stream an insect entrained in the air stream while enabling the air stream to 'flow freely therethrough.

The air suction causes a closure member flap 26 to deflect inwardly from an. initial closed position and j 0. to enable an insect entrained in the air stream to be I carried into the cartridge. 'An inner surface of the cartridge body is preferably coated with a pressure sensitive adhesive of one of a well known type used with the well known flyjtrap papers or other well known adhesives. The closure member flap 26 is preferably formed to fit snuglyf with the inner wall of the cartridge body. It may,;as shown in Figure 4, be mounted to a support body which support body is positioned with the flap within the. cartridge body. The flap 26 in one embodiment ;has essentially the same configuration as the cross sectional configuration of the duct member and is anchored to the duct member, as shown in Fig. 2, by a ring shaped support body The thin, flexible, flap body, 26 flexes from an initial closed position inside' the tube as shown by dashed line 27a to provide an 'entrance through which the insect is carried by the 'air stream. Flap 26 is automatically restored to its initial closed position 27b when the air stream terminates thereby entrapping the insect within .he cartridge.

3Q.

Another embodiment of .the closure member flap configuration, as shown in Figure 4, is trilobal having the shape of a heart valve. As the air stream 11 J 1

B

1 1 i, flows, the closure member' opens inwardly and the trilobal shaped flap segments 28'flex inwardly under the force of air stream suct. As the air stream suction terminates, the flap segments 28 are restored automatically to their initial position thus inhibiting escape of the insect' from within the cartridge through the cartridge inlet.,' It is desirable that a flap such as the trilobal" f l ap have a thickness in the range of about 2 to 20 mils and preferably in the range of 8 to 15 mils and the thickness from the tip 29 (Figure 4) of the flap to its base portion may vary in the range from about 1 to 5 mils or more to facilitate the flap opening and closing when the elastomer of the flap has a Shore A hardness of about to 75. This thickness variation may be achieved by inclusion of an annular ring of elastomer near the base portion 30 of the flap' but may preferably be formed by molding or die' cutting from a sheet having the' desired thickness variation also. For the relatively larger insects such as hornets, the harder Shore A plastics, i.e. those with a Shore A hardness in the range of about 70 to 85 are more desirable. It should be appreciated that the closure member flap may be made of various flexible polymer plastics and the thickness and Shore A hardness will vary, depending upon such factors as whether the flap is a unitary body or is segmented such as being trilobal or quadralobal, as well'as thea thickness and inherent flexible and hardness properties of the elastomer or S 30. polymer plastic.

Referring now to Figure 3, the cartridge 17 is shown positioned in an outermost duct member comprising a telescoping tube 32., In this embodiment the car- 1 2 12

tridge 17 is shown positioned adjacent an outlet end 34 of tube 32. Cartridge 17 can be removed by initially removing tube 32 from the device and then r'moving the cartridge from outlet end 34 by applying 5. force which overrides friction forces established by gaskets 35. These preferably comprise a pair of spaced apart O-rings. The cartridge 17, at the time it is to be discarded, can be removed from the tube 32 by grasping it with a finger and pulling it from the tube. For facility in placement of the cartridge in the tube 32, the tube includes an inner annular recess, not shown, formed in its inner surface to seat and to retain the O-rings 33 ;in a desired location.

In addition, it may be desirable' to have deflectors 33 in the entry to the inlet of the tube to enhance the air flow or increase its velocity.

In the embodiment of Figures 2, 7 and 8 the cartridge is assembled inside the duct member of outer telescoping tube 32 by using the body of tube 32 itself as the component elongated boby of the cartridge. The elastomer flap closure member 26 is positioned inside the tube-and is spaced in the range of about 2 to 4 inches from, the inlet aperture 21. It is anchored to the inner wall of ,tube 32 at an edge segment 35 thereof by an adhesive or by a flange 36 as shown in Figure 2. A filter means, as for example a fine mesh screen 37 adapted |for filtering insects to be captured from the air stream, is placed adjacent an outlet aperture 38 of the tube and is retained in the tube by annular flange 39. It is desirable to position a pressure adhesive 40 which contains an insectide, preferably of the'class which is relatively non toxic to humans or pets., over at least part of 13 t I 1F e 1 i F it Cra~ aJ 1i'j k I the inside surface of the tube 32 between the screen 37 and the flap 26 for retraining entrapped insects.

It is also desirable to space apart the adhesive coating from the point of maximum inward movement of the flap. Usually a spacing of about 1 to 2 inches is desirable. This construction provides a readily disposable-replacable cartridge,.yet enables pests to be collected and to be'discarded without presenting an unsanitary and unsightly condition.

In the arrangement as; shown in Fig. 6, the invention provides for a 'tube 44 having a dust collector 45 used with 'conventional sweeper/vacuum cleaner attachments 46. This dust collecting tube may be discarded and be replaced/with a replacement dust collecting tube or in some cases, a bag or a tube containing the pest collecting cartridge. The arrangement of Fig. 6 thus permits the motor-fan device to be used alternatively as a pest collector or as a dust collector.

i0. Referring now to the alternative embodiment of Figures 7, 8 and 9, an elongated, wand-shaped pest collecting and disposal device of the invention is shown to include an array of 'alongated duct members.

The pest collector device is shown fully extended for catching insects in Figure 7. and fully retracted for storage in Figures 8 and 9. iFigure 9 .illustrates the device of Figure f with retracted duct members stored in a storage reck 52 and having a pluggable battery charger 47 associated therewith 'for coupling to the batteries and for maintaining. "them in a charged state. The device is thus ready to be removed from the storage rack 52 for use. 14 :I:

tI 1' i j ~cl i:i I "i I i jl f ji Referring now to Fig. reference numeral 53 uadignates a first elongated duct member which houses a receptacle 54 for receiving a plug from the battery charger 47, a battery compartment 11, a compartment for motor 8a and a compartment for fan 7. Duct member 53 is mechanically coupled to :a second elongated duct member 55 which is partly positioned within duct member 53 for sliding telescopic movement and engagement therewith. A third elongated duct member 56 is mechanically coupled to and, partly positioned in duct member 55 for sliding telescopic engagement therewith. Duct member 56 preferably houses the disposable cartridge 17. Duct member .56 .also has mounted to a distal end segment a nozzle, 15. Alternatively, a sweeper attachment may be;fitted thereto as is shown in Figure 6.

The arrangement of 'the first duct member 53 can be more readily seen in 4 Figure 10 where a battery compartment is adapted to- receive a battery 11. A receptacle 54 for a plug, of battery charger 47 is positioned at an end segment 54< The battery compartment is adjacent the motor area 8 followed by the fan 7 and an exhaust outlet 57. Forward of the fan 7 is a compartment 58 (Figure 11) 'for receiving and storing the telescoping tube shaped ,duct members. Although the tube shaped duct members 'are shown to have an essentially circular, cross 'sectional configuraLlon, they may also assume other suitable cross sectional shapes, such as rectangular or oval. Grooves 59, as best seen in a cross section view of Fig. 16, are provided to guide the duct,' members in their sliding telescopic motion within,each other and are turned to I, r b 4 4 4

lock in position. The external' and internal dimensions of the duct members are provided to both enable sliding engagement and to provide an air-tight fit without the use of sealing gaskets or O-rings. Duct member 53 can comprise a single body or it may be formed from a plurality of bodies. Generally, it is formed of two bodies which enable the charger receptacle, batteries, electrical connections, motor and fan to be placed therein.' 'The bodies are then fastened together by screws, belts or snaps. An extension tube or cartridge may have snaps 60 (Figure 11), detents or spring loaded leads that lock in the grooves when twisted to retain the tube in the desired degree of retraction orextension.

Fig. 12 illustrates 'the duct member 55 with snaps or detents 60 with 'respective tapered ends 61 and 62. The taper of ends 61.and 62 are sloped at an inverse angle to enable the duct members 55 and 56 to be fitted one within the other as shown by the expanded view of Fig. 12. Likewise Fig. 11 shows the first duct member and second duct member in an ex- 4 panded view. The steps 63 located within the first duct member limit inward movement of the extension tuba. Recessed ring 36,receives snaps 60 to retain the first extension in its fully extended position.

Fig. 13 illustrates a disposable duc member 56 with outlet and inlet tapered ends 61 and 62, respectiveiy and with the cartridge formed by using the tube body as a compartment of the cartridge. The tube has tapered ends 61 and 62 to facilitate engagement with a preceding telescoping, duct member and to receive the nozzle 15, respectively. In this embodio 1 ment the nozzle 15 fits inside the tube 56 and the nozzle safap or detent engages a recessed groove 36 to provide a rigid insect catcher. Alternatively, a detent hole may be provided to receive and engage the snap 36. The cartridge has a coating of adhesive a tension valve 65, as in Figure 4, korir.ng an inlet closure member and a filter 66 for removing entrained insects ieom the air stream.

In Figure 14' there is illustrated a fragmentary view of the motor compartment with an enlarged fan section 67 housing a fan with relatively long blades 68 within a gently sloping housing surface segment 69 interconnecting the motor area and the duct storage area 58. The, housing includes an outlet o0o0 71 for exhausting the air stream from the housing.

While the tubular duct members may be formed of an 2 optically opaque polymer, plastic material, it is de- Sirable that the disposable cartridge be formed of a transparent or partially' transparent material to readily indicate when the cartridge need to be replaced. In one embodiment the cartridge is extruded from transparent plastic. The insect adhesive is then compounded with a pigment and the Interior of the cartridge is then coated "with 'the pigmented adhesive.

A segment of the interior surface remalins free of the adhesive to, provide a window 70 for viewing the interior for collected insects.

There has thus been described an improved pest collection and disposal device. An improved cartridge for use with the device Ls also described. The device is advantageous in that it jfacilitates capturing pests from both accessible locations and from inac- 17. i, I r I I

I

cessible locations with an expandable array of telescoping duct members. The expandable array can be retracted for storage. The improved cartridge disclosed herein automatically captures and restrains insects entrained in an air stream and facilitates the sanitary disposal of insects thus entrapped. The cartridge may be a separate body positioned in the air stream at a cavity of the housing, it may alternatively be positioned in a duct member including a telescoping duct member and it may alternatively be formed with a disposable duct member as a compartment of the cartridge. The device described is advantageously provided with a housing having a handle grip and it may be formed as a wand shaped device with telescoping duct members.

Although there has been described herein particular embodiments of the invention, it will be apparent to those skilled in the art that variations may be made thereto without departing from the spirit of the invention and the scope of the appended claims.
